Description

The The invention relates to the integration of light emitting diodes in building areas, preferably important public Areas such as road markings and highways, on airfields, in swimming pools, on facades and the like desired and / or necessary.

Consists the need, Enlightenable markings in building parts with low cost outlay and bigger Integrating brightness is very often done with integrated luminaires built in light-emitting diodes, such as those in the Internet presentation a company We-ef are included and exemplified under the type designation ETR 159 are offered. These lights are made of a watertight, essentially rectangular or round housing, depending on the dimensions additional on-site expenses up to foundation measures requires. Execution such illumination is finite and at longer lengths of illuminated markings a sufficient variety of lights according to the desired Form course of such markers. For repairs or even destruction is the light under certain circumstances completely change. The expenses for the installation of such Luminaires are significant.

When Ground marking has already been proposed, brick-shaped building blocks made of plastic, which are hollow for the purpose of electrical installation and where a side surface translucent and dismantled trained is. As lighting become conventional Bulbs with usual Mains voltage operated used.

in this connection These are building units that are used for lower lighting technology Claims and preferably be retrofitted in the home. Problematic the protection against penetrating moisture.

To a company publication of the company Kiss, D 58455 Witten, it is proposed translucent building blocks made of plastic for marking purposes, are cast in the light-emitting diodes to insert in building areas, whereby the dimension of the building blocks adapted to the surrounding assortment is and if a defect in the system, the block to be changed got to.

at All previously named construction requires the existing design the luminaire unit, the adaptation of the construction and a larger execution lengths Multiplying the effort for the installation of a lamp.

To DE-OS 10 2004 005 371 A1 is therefore proposed a platform to equip, that in the precast concrete parts that make up the platform, recesses are introduced or introduced locally. In these recesses become commercial Luminaires in which LEDs are used as light sources, or light-emitting diode bands in U-färmige made of plastic tubs and glued these and elsewhere fixed relocated. The lighting units are in their length oriented to the dimensions of the concrete parts and to achieve greater Lengths through Connecting elements coupled together. That too can be a variety of point lights. A cover is made by not closer described and glued running plates.

task The invention is therefore a luminaire assembly using to create light-emitting diodes, for a repair-friendly is and in which an adaptation of the lamp unit to the installation conditions is given, so that new applications by simple change the shape and / or an almost infinite execution length for such lights result.

The Task is solved by an arrangement according to Claim 1, wherein applied to the light exit surface a wear protection layer can be.

When Plastic profile is preferably used polyethylene hose, the translucent accomplished is and also preferably a reinforcing insert to increase its static stability can have. That's usually a spiral running and in the wall integrated steel insert.

The used translucent Plastic profile is regular clear translucent executed but also in cases where a certain color of light is predetermined, already colored.

The provided reflective coating with the effect of a concave mirror can be located on the lower side of the intended light exit Be mounted outside or the lower inside. It can it is an example of a reflective foil or a high-gloss aluminum shell act. But it can also be used as a painting after having its drying reflective properties.

A further proposed variation provides the statically stable translucent Body out a hardened, in the processing state pourable Polyester resin consist perform. Of the Advantage is that with milled recesses in the zu changing Structural parts all tolerances are compensated and gluing with this is given.

Become predetermined recesses or recesses that adapt to uneven floors have to or even in facades, equipped, it may be advantageous the statically stable translucent body from a prefabricated to perform flexible plastic. It is about in most cases around a flexibly adjusted plastic based on PUR.

Becomes a prefabricated static stable at least to the light exit side used translucent body, this can also running in its longitudinal direction and be executed in several parts across its width. Will this one Upper and a separate lower shell used, the lower shell also from a subordinate material, for example In-situ concrete, manufactured.

In order to the diode boards can not twist in the plastic profile and the light-emitting side always points towards the light exit side, can this be fixed. The invention provides for the achievement of this objective before that the plastic profile therefore extending in the longitudinal direction has its inside grooves between which the diode boards be inserted. It is also possible to be on a tip use fixed square plastic profile and the diode boards massive to do so that they are made in width almost equal to the inner Diagonalmass. This is also a twisting of the diode boards in the plastic profile prevented.

A Wear on the light exit side of at least the light exit side translucent body could cause static problems. Likewise, scratches would be charged the illuminance impact. The invention therefore provides that the light exit side the translucent body wearing a wear protection layer. These preferably consists of a mixture of glass beads and a, for example by means of a hot air blower, fusible hydrocarbon resin. This will be the surface the translucent body strength moderately stabilized without any impairment of the light intensity occurs. It is also possible the basic mixture before processing further the roughness increasing scattering elements to mix, for example, in strong passenger traffic for this a danger is not given by slipping.

The Glass balls are preferably in diameter ranges between 1 and 2.5 mm diameter, with a mixture of 8 parts glass beads and 2 parts of resin proved to be useful Has.

It is also possible to run the diode boards like this that these with colored different individually controllable diodes accomplished are. Likewise such variants appropriate be in which the diodes of a diode board in a color and the diode boards are color-coded different controllable sorted installed are.

There the power consumption by the diodes used is low, offers It is on, as far away from a possible by cable sufficient self-sufficient power supply the arrangement power supply side with a memory unit to connect, at least temporarily, of photovoltaic elements fed running is.

It is appropriate, at least the elements provided with light emission are UV-resistant perform.

With the aid of the solution according to the invention, it is possible to subsequently integrate illumination devices with high energy efficiency in all structural areas of sufficient strength after the introduction of corresponding recesses. It is irrelevant whether the recesses are subsequently introduced, for example by cutting or milling, or from the outset. The inventive arrangement may be carried out in terms of their longitudinal extent substantially plane-parallel and almost infinite, ie in the form of a uniformly wide infinite light band. It is also possible, for example in a street, to introduce other forms of illuminated marking, for example in the form of an arrow, without the need for fundamental technological changes. Likewise, the introduction of such an arrangement, for example in a swimming pool over its entire width is possible by the inventive arrangement is embedded in a groove in the ground and the ballast necessary for the diodes is located outside the basin. Apart from the fact that a change in the color of the light produced is readily possible, the inventive arrangement is equally important for the equipment of airfields, railway stations, public roads and the like public buildings, because it is not only waterproof, but also passable and accessible. By inserting the interconnected Diodenplati NEN in a plastic profile is in most cases a longitudinal extent also the repair of a diode board, if necessary, possible in reducing previously known expenses. The use of plastics which can be cast in the processing state results in intimate bonding, for example with respect to the surrounding asphalt. The subsequent application of a wear protection layer, as mentioned, leads to the sealing of the surface. If there is sufficient coverage of the plastic profile, even heavy traffic is possible without affecting the arrangement. The application of a particular consisting of glass beads Verschleisschutzschicht has also proved to be advantageous as lighting technology. Likewise, can be reacted by the inventive structure of the proposed arrangement in a background with different height level, without resulting in negative effects on training and / or function.

The Invention will be explained in more detail below with reference to two embodiments.
